3.18.0118

New functionality
• Added $deliverycontactperson$ + $deliverycontactemail$ to email-variables

Bugfix
• When making a copy of a variables placement/position that has tab-functionality defined the updates of this placement also updated the original placement. There also was a problem that it would not accept saving settings unless a rotation + stroke-width was defined for the tab-position. This has now been fixed.
